Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
te sach » toc sach
danh vi » hanh vi, dinh vi, danh di
va danh » va dinh, va dan, va hanh
cac xuc » cam xuc, cac nuoc, chat xuc
cuu tre » cua tre, cau tren, cau treo
hieu ve » hieu va
nang ma » tang ma, sang ma, nang cao
xuc va » duc va, tuc va, luc va
vi cuu » vi luu, vinh cuu

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((nang x) OR (nang ma)) hoi. ((hieu ve) OR (hieu van)) cac xuc va danh vi cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((nang x) or (nang ma)) hoi. ((hieu ve) OR (hieu van)) cac xuc va danh vi cuu tre~".
• Adding a wildcard symbol may retrieve word variants: te sach y ((nang x) or (nang ma)) hoi. ((hieu ve) OR (hieu van)) cac xuc va danh vi cuu tre*.
